President Trump is threatening to use "overwhelming force" against Iran, after Tehran lashed out at the U.S. over the latest round of sanctions against the regime.
"Any attack by Iran on anything American will be met with great and overwhelming force. In some areas, overwhelming will mean obliteration," Trump tweeted.
Later at a White House event, Trump said he's prepared for whatever happens next with Iran.
